Sealed compressor and refrigeration device
View Patent ↗There is disclosed a sealed compressor in which a compressive component housed inside of a sealed container comprises a block, a suction valve, a piston, and a suction muffler, the suction muffler including a muffler body defining a muffler space and an outlet tube communicating the muffler space with the suction valve, the outlet tube having a bent portion bent in a middle portion between an opening exposed to the muffler space and an opening in a vicinity of the suction valve, a first outlet tube portion extending from the bent portion toward the muffler space, and a second outlet tube portion extending from the bent portion toward the suction valve, wherein a close sided space is formed in a vicinity of the bent portion, the close sided space having one end in communication with the outlet tube and the other end closed.
1. A sealed compressor having a sealed container housing a compressive component driven by an electromotive component, the compressive component comprising:
a block defining a compression chamber;
a suction valve disposed at an end of the compression chamber;
a piston which makes a reciprocating motion inside of the compression chamber; and
a suction muffler defining a muffler space communicating with the compression chamber, the suction muffler including:
a muffler body defining the muffler space; and
an outlet tube communicating the muffler space with the suction valve, the outlet tube having:
a bent portion bent in a middle portion between an opening exposed to the muffler space and an opening in the vicinity of the suction valve;
a first outlet tube portion extending from the bent portion toward the muffler space; and
a second outlet tube portion extending from the bent portion toward the suction valve;
wherein a close sided space is formed in the outlet tube above the bent portion, the close sided space having one end in communication with the outlet tube and the other end closed.
2. The sealed compressor according to claim 1 , wherein the first outlet tube portion is formed to be inclined downwardly toward the muffler space vertically from the bent portion, and the close sided space comprises a bottom portion being inclined downwardly toward the first outlet tube portion.
3. The sealed compressor according to claim 1 , wherein an angle defined between the lower portion of the first outlet tube portion and the bottom of the close sided space is 135° or more and 180° or less.
4. A refrigeration device equipped with the sealed compressor according to claim 1 .
